The [wiki:PumaService PUMA Service], hosted at the University of Reading, provides centralised access to the UMUI, [wiki:FCM Flexible Configuration Management] (FCM) system, and hosts many source code repositories (UM, NEMO, CICE, !GungHo, etc) and associated Trac systems. More recently CMS has installed & configured the new Rose & Cylc systems required for the next generation (vn10.x) of the Unified Model. Rose provides a configuration editor, application runner, suite scheduler (Cylc), log viewer, suite storage and discovery, as well as other suite utilities. In 2015 the Met Office launched the Science Repository Service (MOSRS). PUMA has been set up to enable access to the code repositories hosted on MOSRS.
